This is a great AirBNB with access to all sort of services, check in is easy and there is a free ferry to get you across the river. Make sure you go to the sixth flr and check out the pool.
Lots of street stalls near by on both sides of the river and doormen are most helpful.
I was very impressed with the unit and the views, even from the dunny.
The train is just across the river so access around Bangkok is easy, a tuk tuk from the Palace is around 150 to 250B. Lots of taxi's out side the units as well, long boats and ferry's across the river.
I would certainly select this unit again
